IPTV FAQs                                         
Answers to frequently asked questions about Klicktv IPTV systems built around Exterity IPTV products.

Q: I have seen references to TVIP, Lan TV, TV over IP, desktop TV, Ethernet TV and TV streaming. Are these the same as IPTV?

A: Yes, the basic technology of IPTV is referred to by many different names. Apart from TV streaming, desktop TV, TV over IP and Ethernet TV and Lan TV it is also sometimes referred to as network TV.

Q: How will the TV traffic impact on our network?

A: All TV and video channels are multicast across the network so the level of traffic does not increase with the number of viewers. It should be assumed that all channels will be present on the backbone of the network and the amount of traffic generated can be calculated as the number of channels multiplied by the bit rate per channel. For example, if 10 channels are required at a bit rate of 4.0 Mbps, (Megabits per second) the bandwidth utilized will be 40 Mbps. Multicast management protocols ensure that streams which are not required on a particular network segment are not forwarded to that segment. This means for instance, that only one stream is present on the local switched connection to an individual PC running IPTV because only one channel is displayed at a time on that PC.

Q: Can we choose which channels we have enabled?

A: Yes. An Exterity IPTV TV distribution solution allows you to create a tailored channel selection.

Q: Can different employees have different channels enabled?

A: Yes. A Klicktv IPTV system has a password protected administration system through which you are able to set who has access to which channels.

Q: How many of our employees can watch at once?

A: As many as you wish.

Q: Will an increase in users affect our network?

A: No. Because the IPTV system uses Multicasting to distribute the video streams you can have as many users connected as you wish and it will not make any difference to the amount of bandwidth used.

Q: Are there any security issues associated with having IPTV on our network?

A: No. A Klicktv IPTV distribution system installed on a LAN is completely secure with connections only between the IPTV equipment and your LAN. It does not depend on external connections.

Q: Can we watch IPTV in full screen on a PC?

A: Yes. The Klicktv IPTV systems allows you to adjust the video image to fill your display screen.

Q: Can we have the IPTV user interface customised to our corporate brand?

A: Yes. The Klicktv IPTV user interface can be customised to include your corporate colours and branding.

Q: Can we view IPTV on our TVs as well as on our PCs?

A: Yes. An IPTV Receiver connects any type of display screen to a data network outlet where you wish to display the IPTV service.

Q: Is it possible to record programmes?

A: Yes. The Klicktv IPTV system allows individual programmes to be recorded instantly or according to a schedule. There is also the option to continuously record channels so that any particular programme within the record period can be retrieved retrospectively. Programmes recorded in any of these ways are stored on an integral Video on Demand server from which authorised users can play back the programme with fast forward/reverse and pause control.

Q: How easy is it to add more channels in the future?

A: Adding channels to a Klicktv IPTV system is simple. Just add another IPTV encoder for a local source or gateway module for Terrestrial or Satellite channels and plug it into a spare port on your network switch.

Q: Are there any distance limitations?

A: Distance limitations are the same as for standard Ethernet. Wherever you can install a data network outlet IPTV will work.

Q: Is there any difference in quality when viewing IPTV compared with traditional TV distribution technologies?

A: Yes. The streaming video channels of IPTV are digital which means they do not suffer the deterioration caused in traditional analogue distribution systems producing a noticeably better quality picture. An IPTV Gateway streams the TV signals received from Freeview or satellite without change which means the quality is exactly the same as transmitted. IPTV encoders with either analogue or digital inputs in a variety of formats can be set to stream at a high rate for highest quality or a low rate for minimum bandwidth.

Q: We have a TV source at one site which we want staff at another site to see. Can we do this?

A: Yes. The streamed channel can be routed over a WAN link to the remote site where it can be made to appear as a channel on the IPTV distribution system at the second site in the same way as the first.
